Back in July 2022, the Jet Zero Strategy was rolled out to bring together experts from the aviation and aerospace sectors, academies, innovators, international partners and the public.
The strategy was to form a Jet Zero Council that can work together to prevent the aviation sector from becoming one of the largest emitting sectors by 2050, and instead secure a more sustainable outlook. It was discussed that goals should be set for all domestic flights in the UK to become net-zero by 2040, and for all airport operations in England to produce zero emissions by the same year.
Ultimately, the intention are that the success of aviation must no-longer damage the planet. To do that, the aforementioned bodies are working towards creating new jobs and developing new industries with innovative new technologies that improve energy security across the nation.
Since its formation the unity has already made great progress, aiding the creation of sustainable aviation fuel (SAF) in the UK, which is produced by Phillips 66®. Commercial airline Jet2 have been utilising the fuel since 2023 and have managed to reduce their carbon emission by 80%. However, there are much more innovations needed to establish a more confident path towards net zero for the sector as a whole.
Commercial waste collection experts Skips and Bins, recently investigated other innovative efforts being and tested to help aid aviation commercial waste and sustainability goals.
Fuels
SAF
SAF has already brought improvements to the sector. It is made from a variety of feedstocks. These feedstocks can be created from domestic and commercial waste, or from recycled carbon fuels (RCFS) and animal waste. The British government has committed to incentives for producing SAF from wastes, residues or low carbon energy, which places the UK as the current global leader for the development, production and use of SAF.
By the end of 2023 the UK had invested in 26 million litres of SAF. This ultimately lead to the RAF flying the first wide bodied plane in the world running on 100% SAF transatlantic flight, which took off from London to New York at the end of 2023.
Lignin polymer
Scientists at Washington State University (WSU) have demonstrated a potential fuel that comes from the conversion of lignin polymers, which is the main component of plant cells. It was discovered that it can be used to as jet fuel and aid the performance of sustainably produced aviation fuels, if rolled our commercially.
Lead scientist and Professor of WSU’s Department of Biological Systems Engineering, Bin Yang, commented saying: “Our achievement takes this technology one step closer to real-world use by providing data that lets us better gauge its feasibility for commercial aviation.”
Lignin polymer, which makes up the tough and sturdiness of plants, would make sustainable fuels cleaner and more easily usable in jet engines because it is dense, efficient and has seal-swelling qualities. The end goal is that hydrocarbon catalysed from lignin could effectively replace fossil fuel-derived compounds, which are called aromatics.
